Adventure Games: The Volcanic Island, by Thames & Kosmos

In this cooperative game, you take on the role of four students traveling together on a remote and mysterious island. You are looking into some strange events that have been happening — incidents that the police believe are natural occurrences, things to be expected on a volcanic island such as this. But is everything really as normal as it seems? Or is there something else behind what is happening at the volcano? How the story ends is entirely up to you.
